[ASTERIXDB-2584][FUN] Support rounding digit for round()

- user model changes: yes
  - user can pass optional 2nd argument to round() function
  to specify the digit to round to.
- storage format changes: no
- interface changes: no

Details:
- Added new descriptor for 2-arguments version of round().
- Converted evaluator class to named class, now used  by both
round() descriptors.
- Added test cases for 2-arguments version and invalid cases.

+/**
+ * This function rounds the numeric values. It receives 2 arguments, first is the numeric value to be rounded, second
+ * is an optional parameter to specify what digit to round to. If the provided rounding digit is positive, then the
+ * rounding should be at digits to the right of the decimal point, and if the rounding digit is negative, then the
+ * rounding should be at digits to the left of the decimal point.
+ *
+ * The return type behavior is as follows:
+ * int8, int16, int32 and int64 -> int64 is returned
+ * float -> float is returned
+ * double -> double is returned
+ * others -> null is returned
+ *
+ * Below is the formula used for rounding in the possible cases:
+ *
+ * Case 1: rounding digit is not provided or 0
+ *  - Normal Math.round(123.5) -> 124
+ *
+ * Case 2: rounding digit is positive
+ *  - multiplier = 10 ^ digit
+ *  - Math.round(value * multiplier) / multiplier
+ *  Example:
+ *      - round(1.456, 2)
+ *      - multiplier = 10 ^ 2 = 100
+ *      - value = value * multiplier = 1.456 * 100 = 145.6
+ *      - value = Math.round(value) = Math.round(145.6) = 146
+ *      - value = value / multiplier = 146 / 100 = 1.46 <--- final result
+ *
+ * Case 3: rounding digit is negative
+ *  - multiplier = 10 ^ Math.abs(digit)
+ *  - Math.round(value / multiplier) * multiplier
+ *  Example:
+ *      - round(1255, -2)
+ *      - multiplier = 10 ^ Math.abs(-2) = 100
+ *      - value = value / multiplier = 1255 / 100 = 12.55
+ *      - value = Math.round(value) = Math.around(12.55) = 13
+ *      - value = value * multiplier = 13 * 100 = 1300 <--- final result
+ *
+ * Important:
+ * When dealing with big round decimal points, there is a potential of precision loss.
